Still cant figure out the gurgle, i'll take to dealer tomorrow. While i was under the hood examining wut was wrong with my car, i was wondering if its possible to reroute the stock intake plumbing. I've seen it done on my frends integra and improved his performance quite a bit on the butt dyno. I was thinking of taking out the resonator box and cutting off the front part of the scoop just until the rectangular tubing part. If i went to home depot and used some piping to run air from the location of the CAI such as PR to the tubing where the scoop used to be, would it improve performance?

 

Anything's possible! Muuuaaahahahahha!!!!!

Lotsa options here - use searches for intake or mid-pipe or airbox or OSCAI & you'll find all you want and more.

I have a hybrid OSCAI with a K&N panel filter & like it just fine. The majority of the stock intake plumbing is gone now.

Sounds great & a slight boost in performance. With intake mods, it's mostly a sound thing, though. That's the main benefit. To the ButtDyno6000, it "feels" faster, mostly because it "sounds" faster.

 

Like KWheelzSB said intakes dont really give your car much power they are just really for the sound which makes you think your car is faster..Intakes will typically give you little horsepower, but hey the sure sound great

If you follow the snorkel, starting at the mouth you will notice a pipe that extends from this and runs under your battery. That's the first resinator. I unhooked this and ran a 3inch pipe (from the snorkel) under the car that faces forward into a 4inch opening; that is fed by the ton of air that rushes under your car, this along with the stock mouth of the snorkel should feed the snorkel piping all it can handle

The second task was to feed the throttle body all it can handle. The problem is that the opening of the snorkel in the stock air box is about 2.25 inches, but the opening in the stock air box that feeds the throttle body is about 3inches. To over come this I drilled a 2inch hole in the lower half of the stock air box, adjacent to the opening for the snorkel (I got the idea after looking at the intake of the Saleen S7, and since it is in the lower half it is still filtered by the K&N panel that I have in the stock air box), I had run piping to the PRCAI source, but after doing comparisons on the temp of my intake manifld, it really doesn't make a difference if you just leave the hole with no piping, it is pretty much blocked from heat from your engine, and the space around the hood is where most of this air will come from. You can also get an idea of how a hybrid intake would sound, this will make your car growl when you get on it.

Then I made my own midpipe, for this application and the next, I have the link how to make your own midpipe, just PM me (I'm at my girl friends house and don't have acces to my favorites list) you can do it in about an hour, parts are from loews, cost about 15.00.

Now I am getting a JWT filter (for the velocity stack, and to keep the intake path straight) keeping the lower half of the stock air box (I have another one that is stock with no hole on the adjacent side) and leaving the snorkel and ram air that runs under the car in place. I am positioning the filter right over the ram air source and will put the intake temp senosr in the path of the cooler air.

This seems like a pretty sound setup, if you have any questions let me know.

 

to dumb it down, more air is always better...
if you want more air to go in, with little effort, don't cut anything,
just buy a K&N filter...or, you could search on here for home-made
intakes - I know there's a bunch.

Here is the link, I found it in another thread

To make the midpipe
http://www.drwebdesign.com/mymaxima/upperintake.html

You can use this for the stock application, or if you want to attach a filter without having to buy a MAF sensor bracket
http://www.vqpower.com/v2/modules.ph...howpage&pid=35

Fabricating and expriementing with intakes was really fun and rewarding, and it cost me about 30.00 total (minus the JWT intake)for all of the above, and that includes painting the midpipe, and ram air pipe, the color I wanted. The best part is that I can put it all back to stock in about 5 min should I ever need to take 'sweetness' in for warranty work.

If you do this, the first thing I would do is run piping from the first resintor on the snorkel (you can take off the pipe that runs from underneath the snorkel to the resinator under the battery without having to take anything apart, just work it back and fourth, or if you want the easiest mod for the max don't attach a pipe to it, it will get the same air as an Injen, and give you a nice little hiss at WOT), then make your own midpipe, then see if you can find a lower half of the stock air box at a salvage yard or from an org member(should cost about 10-15.00.) should you decide to put a hole in yours.

If you have any other ideas, or questions let me know, the intake is the easiest mod to do yourself next to installing clear corners and shaving your rear emblems.

 

So your saying the best thing to do is disconnect the whole snorkel, that goes under the battery, from the stock scoop? Or are you saying to disconnect that snorkel and fabricate a pipe to the scoop and run it under the car? If anyone has pics of this i would greatly appreciate them

Keep the snorkel, just disconect the little pipe that runs from underneath the snorkel to the box under your battery. Then if you want to attach a pipe to this and run it under your car it will give you a little more air. I had some pics taken over christmas but they all havn't been mailed yet. Just get under your hood and you should see what i'm talking about. Please let me know if you have any questions.

 

So by disconnecting this little snorkel...the fans will blow air straight in the scoop...right to the intake?? Is that what the goal is by just taking out the little curled snorkel?

Thanks,

-Nick

 

The goal is to have a second air source for the snorkel. Like I said this is the same air that the Injen gets. Ideally I would route piping from this source (on the snorkel) straight down under your car. That way the feeds for the snorkel would be the stock mouth which is getting air from the front of the car, and the new source located under the car that gets the ton of air that flows underneath your car.
Did you see the little pipe that I'm talking about, it connects close to the mouth of the snorkel (underneath) and runs toward your battery. Like someone else said, an intake will give you more noise than power, but every little bit of air helps. This mod is for a little more air but more for a nice hiss when you go WOT, thats why that little box is there under your battery, to keep the intake quiet. Any more ?, let me know.

 

Thanks for all the help...my last question for you is what kind of piping did yuo use to run under the car and where can i get it from??

Thanks for all your help,

PVC, cheap, light, smooth on the inside, well insulated, and easy to paint. (you can get it anywhere, loews, home depot, true value) Get a 3inch pipe, use a 3inch rubber coupler to attach it (to fit it on the snorkel you will have to tighten the hose clamp on the 3inch rubber coupler almost all the way but it will work)

I should be getting some pics soon, so I hope to have that info for you shortly. You might PM me so i can have a record of where to get a hold of you, I have no idea how long it will take to get the pics though, so please be patient.

 

Use ABS plastic piping instead of PVC. It is much more heat-tolerant & has a higher flashpoint. (Also available in the plumbing section of your home improvement store). It's black.

This is Very important for engine-bay applications.

 

I have used this piping for over a year now for both ram air, and midpipe applications. I saw the black piping but they did not have the 3inch size that I needed in stock, so I used the white piping. I have looked over the piping and have noticed no difformities associated with heat, most of that years span was in the summer when it was very hot (and that included three 3hr trips back and fourth to dallas.) What is the difference between these pipes, and what are the precautions.

 

I think I remember someone saying that in high-temperature situations the plastic in the PVC breaks down and releases PVC particles, which get sucked into your engine. Not very scientific, I know, but I'm working off memory here.

 

I find this very false, KINGMAX just found a .41 or so second increase from just adding an APC filter....hes running 14.69's now....

 

I found that post through a search. Someone said that in high temps PVC 'may' release a gas that 'may' be harmfull to your engine. I know that burning PVC releases toxic fumes but I have heard nothing about heating it. I also checked my throttle body (I cleaned it when I installed the midpipe) it is still clean with no residue.

However their were 49 other posts on the org of other people using PVC to make intakes and midpipes, and not one post about those people having engine problems.

I just searched the net. People are using PVC for intake piping from z28's to Z's, I haven't found anything about PVC being harmfull to your engine. In fact on one sight they indicated that a lot of the plastic pieces in automobiles have the same materials as PVC.

I even ran across a post that recomended PVC for an intake because the inside is polished and smooth. I am pretty sure that PVC is OK to use for an intake, (I was unsure before I searched the net) it is pretty thick, and it would take a ton of heat for the inside to get hot enough to smoke.

 

Basically, one will burn more easily - that's it. All the OEM plastic under your hood is of the ABS variety, for safety precautions.

It's less a function of the plastic burning/deforming from ambient heat under the hood and more a function of reducing the likelihood of a major underhood fire, should you have an oil/manifold/electrical or other type of small fire under the hood.

PVC will burn like "Napalm in the morning" if something else starts it going. And if that happens, boy, head for the hills & watch the fireworks from a safe distance - 'cause it'll be one helluva show!

 

Can something be "very" false?

Gravy, man - gravy. It's all good. I love being proven wrong when it benefits me.



(I guess my point was that people shouldn't have HUGE expectations for power from just an intake mod).

 

That's great! I'm going to go tell my max right now, if it ever breaks down or loses to a civic, I will torch it, invite friends to watch and roast marshmellows, then call my insurance to come pay for this piece of sh^t that just had a mysterious engine fire which lead to a totally useless scrap of ash.
